PUBLICATION - Carlos Alcaraz defeats Casper Ruud to win first Grand Slam, become new world No 1

 Carlos Alcaraz won his first ever Grand Slam title at the US Open on Sunday night

, also becoming the youngest man to be ranked world No 1.

The Spanish teenager beat Casper Ruud 6-4 2-6 7-6 (7-1) 6-3.

Both Alcaraz and Ruud went into the match hoping to lift a first Grand Slam title and to top the rankings.

But it was the 19-year-old who came out on top on Arthur Ashe Stadium.

Alcaraz is more than a year younger than Lleyton Hewitt was when he topped the standings in 2001.

“This is something I dreamed of since I was a young kid. To be number one in the world, to be the champion of a Grand Slam.

“ All the hard work I did with my team, my family. I’m just 19 years old so a lot of the decisions are with my team, my parents. It’s something that is very special for me,” Alcaraz said.

Alcaraz admitted he was “a little bit” tired, but said: “I always said it’s not time to be tired in the final round of a Grand Slam. You have to give everything on court, everything you have inside.”
